A baby boomer is a person who was born during the demographic Post-World War II baby boom. The term "baby boomer" is sometimes used in a cultural context, and sometimes used to describe someone who was born during the post-WWII baby boom. Therefore, it is impossible to achieve broad consensus of a precise definition, even within a given territory. Different groups, organizations, individuals, and scholars may have widely varying opinions on what constitutes a baby boomer, both technically and culturally. Ascribing universal attributes to a broad generation is difficult, and some observers believe that it is inherently impossible. Nonetheless, many people have attempted to determine the broad cultural similarities and historical impact of the generation, and thus the term has gained widespread popular usage. In general, baby boomers are associated with a rejection or redefinition of traditional values; however, many commentators have disputed the extent of that rejection, noting the widespread continuity of values with older and younger generations. In Europe and North America boomers are widely associated with privilege, as many grew up in a time of affluence.
